Description
Technical field:
The present invention relates to the stripping method of a kind of PLA (PLA) fiber, belong to after-finishing of textile products technology field.
Background technology:
PLA fiber (polylactic acid) is with starch-containing materials such as corn, Ipomoea batatas, wheats; Be converted into lactic acid through fermentation; The fiber of processing through polymerization, spinning again, it not only has excellent physical property and takes performance, and the ability biodegradation; Being a kind of novel environment friendly fiber of Natural Circulation fully, also is present unique synthetic fiber that do not rely on petroleum resources.
At present, because PLA fibrous glass temperature is lower, and do not have the special-purpose dyestuff of PLA fiber on the market; Because the physicochemical properties that the PLA fiber is unique are in dyeing course, all bigger to the sensitiveness of temperature, pH value, dyestuff; In batch production process, be easy to cause aberration, cylinder poor, do not redye production being caused very big economic loss if do not strip; Because PLA fiber alkali resistance is poor, the stripping method that fibers such as cotton, hair, terylene are commonly used is not suitable for the PLA fiber.
Have based on this, make the present invention.
Summary of the invention:
The objective of the invention is the problem that all the time can't redye to the PLA fiber, remedy the aberration that the PLA fiber occurs easily in dyeing course, cylinder difference problem, thus a kind of stripping method of suitable PLA fiber is provided.
First aspect of the present invention provides a kind of stripping method of PLA fiber; Light fabric is handled; May further comprise the steps: adopt sodium thiosulfate or three pairs of dodecyl sodium sulfate phenyl phosphorus to cooperate penetrating agent JFC to be the liquid of stripping earlier, dyestuff is stripped, wherein the sodium thiosulfate addition is 1～10g/L; Three pairs of dodecyl sodium sulfate phenyl phosphorus additions are 3～20g/L; The penetrating agent JFC addition is 1～10g/L, and then the dyestuff that adapted detergent FK-9503 will float over fabric face cleans, and detergent FK-9503 addition is 1～10g/L.
In the above-mentioned stripping method, cooperate following technological parameter, can make the aforesaid liquid of stripping obtain best treatment effect.
